Prototyping in Product Management
Most people nowadays know, what prototyping means – “prototype” is a Latin word and actually means “primitive form”. But why does it help you in developing better products, what are the advantages? First of all, prototyping reduces business risk. By creating such an “early model”, you are able to develop worthy solutions that solve real problems. Also, it is much easier to communicate and demonstrate the solution to the business as you can actually test something that does not only exist on paper. You can also obtain customer feedback at an early stage that helps you to improve the product before launching it.
